Ultrawideband Signal Passes Data Through Walls

Posted by ryuzaki0 on from the wireless-fight-out dept.

writertype writes "You may already be familiar with ultrawideband; UWB technology has been specifically talked about and designed to replace wired USB connections for over a year. Due to its high bandwidth, it's also been considered as an A/V cable replacement. The problem is that UWB radio performance degrades precipitously, effectively confining it to a single room. Until now, that is. Startup TZero says its UWB implementation provides high throughput through walls. Will this be an effective competitor to 802.11n?"

  1. 3.1GHZ Has trouble going through walls by IntelliAdmin · · Score: 5, Insightful

    The speed increases are nice with this technology. The problem is physics. As it stands UWB runs from 3.1GHZ to 10.6GHZ. Radio in this band operates much like visible light - it is easily blocked by walls and other obstacles. Because of this I think that 802.11b/a/c/n are going to be around for a long time
